AGf/VT 3,086,524 PELVIC CAVITY TREATING DEVICE AND MEDICAMENT THEREFOR Malcolm H. Laws, St. Petersburg, Fla., assignor to Birch and Birch, Washington, D.C., a partnership Filed Feb. 3, 1960, Ser. No. 6,400 4 Claims. (Cl. 128-173) The present invention relates to a medicament and a novel pelvic cavity treating device.

Much concern throughout the world has developed in connection with the education of the masses in the matter of proper pelvic cavity treatment. This is particularly a problem in countries and localities where the poor, ignorant and uneducated classes of people are living in squalor and unhealthy overcrowded conditions, and continue in the face of such difiicult and unhappy conditions to require such treatment, but cannot afford such treatment. With such classes of people there are no safe inexpensive means available to treat the pelvic cavity with maximum efficiency and furthermore there are no means available, which are simple enough for the average uninformed or lay person to use themselves without medical or professional advice.

It is an object of this invention to provide a novel medicament for treatment of the pelvic cavity in combination with a novel manual self-controlled applicator and container unit, which is economical and of such a simple nature as to be controlled by the simple expedient of a push of the users finger on a button or the like to apply the medicament.

Another object is to provide in a package several containers or units loaded with a prescribed medicament adapted to couple with a vaginal or pelvic cavity applicator.

A further object is to provide a novel applicator for injecting prescribed medicaments in a dense spray pattern into the vaginal or pelvic cavity.

Still another object is to provide a pelvic cavity treatment kit of minimum expense and which is comprised of mechanism of maximum simplicity.

With these and other objects in view, the invention consists in the construction, arrangement and combination of parts hereinafter described and particularly pointed out in the appended claims, it being expressly understood that there is no intent to limit this invention to the details of construction illustrated.

In the drawing like parts throughout the several views are given like numerals and are thus identified in the following description:

FIGURE 1 is one form of applicator used for injecting a medicament into the pelvic cavity;

FIGURE 2 illustrates a package containing a plurality of pressurized capsules or aerosol cartridge units loaded with a suitable medicament and having a hollow valve stem adapted to be coupled to the connector end of the applicator of FIGURE 1; and

FIGURE 3 is an assembled view in side elevation of an aerosol cartridge unit in connection with the present novel applicator as it is held in the palm of a users hand for actuation by pressure upon the finger lugs formed from the applicator.

Referring in detail to the drawing the complete kit comprises a package A, a plurality of aerosol cartridge units B loaded under pressure with a suitable medicament and a suitable propellant, as is wellknown in the aerosol industry, and a novel applicator means C for administering the contents of the said aerosol units.

Each unit B comprises any suitable tubular container,

for example, plastic, metal or glass. The selection of container material is made with the view to providing United States Patent 3,086,524 Patented Apr. 23, 1963 economy and facility and simplicity in manufacture and in subsequent loading with a prescribed medicament and propellant. These units are provided with a valve unit 10, which may be of the metered or unmetered type as desired. For example, such valves may be made by the Risden Manufacturing Company Aerosol Division or by the VGA, Incorporated, who make suitable standard type bottle valves for glass, plastic and metal containers.

In some instances the container units are coated internally and externally, but this depends usually upon the medicament used or the propellant.

Extending from the valve body '10 is a hollow valve stem 11 through which the cartridge unit contents discharges into the elongated hollow tube '12 of the applicator C.

The applicator C comprises an elongated tube 12 formed at the discharge end with a cone 13 having a hollow conical bore 14, while the tube 12 at the opposite end is formed with a counter bore 15 in the provision of an annular land 16 to engage the rim of the valve stem 11, see FIGURE 3, to thereby actuate the valve.

The cone 13 is formed with laterally and divergent angularly directed outlet ports 17 and the walls of the tube 12 are for-med with alternately staggered outlet ports 18. Each of these respective outlet ports direct the pressure actuated medicament in a desirable spray pattern outwardly in all directions in the vaginal or pelvic cavity, see FIGURE 1. Also, the cone 13 at the base thereof is formed with an annular rounded rim 19 at the discharge tip thereof to avoid any tissue damaging edges and if desired the cone bore may be reduced to develop additional back pressure to increase the force of the emitted spray.

The cartridge units B may be of sufiicient volume to provide for successive metered discharges of the medicament or the same may be of a non-metered or continuous valve type and the cartridges may be emptied by one application and thrown away after each use.

To use the vaginal or pelvic cavity treating device, a unit B is removed from the package, the valve stem 11 inserted into the counter bore or coupling end 15 of the applicator C with the top of the valve stem contacting land 16, and the assembled unit is then held in the palm of the users hand, as shown in FIGURE 3, with part of the palm at the thumb joint and the index finger curled over the actuator lug 21 of the applicator. The lug 21 projects from the tube 12 to either side thereof for either left or right hand use and when the lug 21 is pulled or pushed toward the cartridge, movement is imparted to the valve stem 11 to open the valve and cause discharge of the container contents from the valve stem and into the applicator C from whence it is projected from the outlet ports 17 and '18 to the walls of the vaginal or pelvic cavity.

Thus there is provided a kit comprised of economical and simple to operate means for applying a prescribed medicament directly to the vaginal or pelvic cavity and wherein the novel applicator in combination with a pressurized spray pattern will thoroughly cover the walls of the vaginal or pelvic cavity and related parts with a thin film of medicament for maximum efficiency.

The prescribed medicament for use with the present apparatus may be comprised of particles in the range of colloids, and of colloidal dispersions in liquids, emulsions, jellies, fogs or foams. The condition to be treated being known the formulation and resultant characteristic of the medicament both chemically and physically may be controlled by the present apparatus. For example, some types of propellants and medicaments may result in a final ejection from the applicator C of either liquid, emulsion, jelly, fog or foam, and there is provided with this combination of a medicament loaded in a container with a pressurizing means, that is, a propellant and a controlling valve and connected ejector unit, a means to treat the pelvic cavity, for example, whereby the final physical formation as Well as the selected medicinal or chemical properties of the medicament may be controlled to provide liquid, jelly, emulsion, fog or foam for the best calculated cavity treatment.

Although only one embodiment of the invention has been illustrated and described in detail, it is to be expressly understood that the invention is not limited thereto and various changes may be made in the specific parts and arrangement and combinations thereof without departing from the spirit and scope of the invention, as will now likely occur to others skilled in the art. For a definition of the limits of the invention, reference should be had to the appended claims.
